What is the difference between capacitance touch screen, resistance touch screen and infrared touch screen of all-in-one touch screen kiosk machine? Touch screen kiosk/All in one machine is generally divided into capacitive touch screen all-in-one touch screen kiosk machine, resistance touch screen all-in-one touch screen kiosk machine and infrared touch screen all-in-one machine. Then their price, function and appearance are very different. Today, let’s find out what the difference is between them.
Resistance all-in-one touch screen kiosk machine
The resistance touch screen query all-in-one machine and automatic full-automatic control system are very cost-effective and have good reflection sensitivity. The office environment is completely isolated from the outside, is not afraid of dust and water vapor, and can take into account a variety of harsh environments. It can be touched by other objects, and its reliability is very good. Because the resistive touch LCD has a certain working pressure as far as possible, it is easy to cause damage to the surface material and damage the common application period of goods after a long time, which is cheap and good.
Capacitive touch screen all-in-one kiosk machine
The key to the structure of the capacitor touch screen query all-in-one machine is to coat a transparent plastic film layer on the toughened laminated glass display screen, and then add a piece of maintenance toughened laminated glass outside the electrode layer. The double glass separation design scheme can completely repair and maintain the electrical conductor layer and sensor. It is obvious that this layer of toughened laminated glass is not heat conduction, The conductivity of the DC regulated power supply is not very good. It is changed to high-frequency communication of AC data signals. An AC circuit is pulled out by the filter capacitor caused by people’s fingers (separated by thin toughened laminated glass) and the working kitchen table. This is the origin of the name of “power capacitor” of the capacitor screen: it is unstable to work by filter capacitor. The method of filtering capacitor is damaged by temperature, gas, air humidity, finger humidity level, body rest, ground dryness level, and is particularly damaged by external large-scale objects, resulting in unstable results. At the level of large models and specifications, the price is relatively expensive!
Infrared touch screen all-in-one kiosk machine
It can use a wide range of landforms, temperatures, gases, air humidity, and has a wide coverage. It has strong adaptability to a variety of climates and application literacy. Not afraid of dust (even a small amount of small stones), liquid (not strongly corrosive), the temperature of most geological structures (at least 30 ℃ below zero and 70 ℃ above zero). The infrared touch screen query all-in-one machine can not be used in bright conditions, but the overall evaluation is cost-effective and is generally used in large specifications.
Based on the above, do you understand why there are many infrared touch query all-in-one machines on the market? Infrared touch query all-in-one machine has high cost performance, so it is widely used by people. If it is not for the special requirements of the project, it basically does not need to choose capacitive touch, because it is expensive and will not choose resistive touch. It is cheap, but there is a certain gap in the use of it.
